WOVEN PILE CARPET..

SPECIFICATION formingpart of Letters Patent No. 691,889, dated January 28, 1902.

Application filed May 22, 1901.

To ctZZ whom, it may concern:

Be it known that I, WALTER BENHAM, a citizen of the United States, residing at the city of Philadelphia, State of Pennsylvania,have

invented certain new and useful Improvements in Woven Pile Carpets, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specifi- Io cation. l

My invention relates to Woven pile carpets; and it consists of an improvement in that class ofsuch carpets known as tapestry and tapestry-velvets, as hereinafter described.

It has for its object to produce such a pile carpet by a new arrangement, relatively, of the pile-Warp with the ground or body Warp and of both of said sets of threads with the usual weft-threads and binder warp-threads for the double purpose of making a more compact woven body and of better securing the pile-warp in the weave, and incidentally of producing a tapestry or a tapestry-velvet carpet, showing the face pattern and its colors on the back thereof.

In this class of carpets, known as tapestry and tapestry-velvets, which differ from each other only that in the former the pile Warp-threads are left uncut in the weaving' while in the latter they are cut, the pile face is formed from printed pile warp-threads and the back of plain body or ground warp-threads with the usual binding-warp and the usual lilling weft-threads; but in the weaving of such carpets the pile warp-threads are so thrown in the reeding that they lie in a horizontal plane above and are superposed upon the ground or body warp-threads; but in my improved carpet of the class mentioned I bring down the pile warp-threads into a lower horizontal plane, so that they lie alongside of the ground or body warp-th reads, and are thereby more compactly and firmly heldin the woven web, the change in the relative position of the body Warp and weft threads to the pilewarp being as hereinafter described.

In the accompanying drawings, Figure l is a longitudinal section, enlarged, of a piece of tapestry-Velvet carpet in which printed pile- Serial No. 61,446. (No model.)

warp is employed, woven in the manner as 5o heretofore and usually practiced; andV Fig. 2 is a transverse section of the same. Fig. 3 is a longitudinal section, enlarged, of the like class of carpets, woven according to my invention; and Fig. 4 is a transverse section 55 thereof.

A clearer understanding of the construction of my improved carpet and of its advantages will best be obtained by a comparison with that now in use, as illustrated by Figs. land 6o 2, in which A represents the set of ground or body Warps; B, the pile warp-threads, and b the cut pile ends thereof; C, the binder-warps, and D the transverse weft-threads. It will be observed that the base of the pile warpthreads lies in a horizontal plane midway in the woven web, entirely above and su perposed Vupon the body or ground warps and of course entirely above the under face of the fabric which, as seen in said Fig. 1, is composed ex- 7o clusively of the ground-warps A, weft-threads D, and binder-Warps C. In myimproved fabric, however, as will be seen by reference to Figs. 3 and 4, I draw down the pile-Warp B, so that a greanter lengthof it will be within the woven web, and these pile-threads are thus brought to a position alongside of the body or ground warps A, between the weftthreads I), the whole bound into the fabric by the transverse binder-warps C. The re- 8o sult of this method of forming the fabric is to give a great-er body and depth of pile-Warp within the woven web, as Vseen in Fig. 3, producing necessarily a thicker carpet, With greater softness and elasticity, while at the same time the pile-th reads are more compactly and firmly held relatively to the body or ground warps by the transverse binder warpthreads. This weave also gives as a necessary incident to its method of reeding sub- 9o stantially a double-faced pile fabric in that the face pattern is accurately reproduced both in design and color on the back of the carpet, an eect which for certain purposes may be most desirable and useful entirely apart from the intrinsic merit and utility above described of this new weave as a fabric.

Having thus described my invention, what the face-pattern of the fabric both in design 1o and lcolor.

In testimony whereof I have hereunto ab xed my signature this 11th day of May, A.

WALTER BENHAM.
